In private practice and in his previous role as Wisconsin’s Chief Deputy Solicitor General, Ryan has secured numerous victories in the Supreme Court of the United States—including three pre-certiorari injunctions pending appeal, which are rare—and in multiple federal and state courts of appeal and trial courts. He also has built national, bipartisan coalitions of states and interest groups in support of several lawsuits and briefing efforts, including a 12-state coalition whose suit against the Federal Communications Commission prompted it to reverse a major new rule. 

Earlier in his career, Ryan worked in Washington D.C. in an elite complex-litigation practice group of an Am Law 10 firm.

Ryan also served as a law clerk on the U.S. Supreme Court for the Honorable Antonin Scalia and on the U.S. Court of Appeals for the Ninth Circuit for the Honorable Diarmuid F. O’Scannlain.
